I am thinking about getting RRM Timing box and RRM underdrive pulley.
Wondering which one I should get first. Which one do you feel more of a performance difference?

 

if these are your first mods, i would say get the pulley, wait a few mods until you purchase the timing box. get more bang for your buck if you have supporting mods with that timing box. but than again i do not have the timing box and cant compare the gains of it to anything.

i notice in your other thread your looking to buy a used pulley. I mean they are so cheap, and the perfomance gain is pretty good for how cheap the product is. so everybody who buys it, usually dont sell it. its an easy install, good gains, and cheap. just buy a new one. that way you'll get a brand new belt with it to. IF you find somebody who wants to get rid of the pulley, than scoop it up, but it might be rare to find somebody who wants to part with it.

 

i'd go with the pulley as well. it was one of my first mods and hasnt let me down since. just get one new cause at least you know you'll get the belt straight from RRM and you wont have to worry about picking up a wrong size one at the store. timing box i'd wait til after a few mods where it'll be more effective since the RRM N/A mods all benefit from each other a little more then on their own.

on a side note: do you really need to start one or two new threads everyday? some of your questions have been covered using the search function

 

agreed on the power per cost gain of the UDP. Its a good buy. I don't use the timing box so i do not have any input on the product.

 

well i already have cold air intake custom ram air, throttle body spacer and bypass, egr unplug, pcv bypass, no header yet, but full exhaust 2.5 inch cat. delete, diy engine bay grounding kit. One person said i needed to have other mods to have real benefits from timing box. Is that correct? well these are the mods that i have. Not really worried on price of them just wondering really which one gives you more power???

 

If the question is giving more power, the timing box is the answer, but comparing these two mods isn't comparing apples to apples. Think of it this way...the UDP "frees up" more power, regardless of supporting mods.

 

When I was talking about the timing box benefitting more mods, I was referring to the fact that all of the RRM N/A mods benefit more off each other. Yes they're good individually but you'll see slightly more gains with everything else that you add on from each part IIRC. But still I would say for now the better option would be UDP to free up the engine a little bit

 

UDP for sure.

 

price not being an object Which one makes for better performance you can feel?

 

Think that i am going with the UDP judging by how many people are saying it, not sure yet.
Well does the timing box adjust the air/fuel ratio at all? Also the more mods you have done already like the ones I said further up on the page, the more you get from a timing box? is that right? So you could get more than 8 hp just depending on what else you have done?

 

I doubt you'll get more than 8hp. If RRM dynoed it at 8hp, I'm pretty sure it's near the top.

Get the UDP men. It's 50% cheaper and you see a great difference. I don't think the timing box adjust the AFR, I think only the piggyback does.

 

rrm told me you can pull more than 8hp with the timing box when combined with the piggyback but thats the same with most mods lol

 

the 8hp is how much power the box adds on its own versus a completely stock ralliart to my understanding. when combined with other mods i believe you gain more

 

Thanks everyone for all the help going with the UDP for now and then timing box later.
Thanks again
